I've been working on this for over a week. I don't think its working the way
it should.

Here's what I'm trying to do:

I have a Windstream dsl router with wireless >
Centos 6.8 server eth0  > > gateway
                                     eth1 > > gateway
Switch > other computers and devices > gateway

I want to send all internal traffic through, all external
traffic through, then back through

I did an iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE


Outside connectivity for all other computers and devices only works if eth0
is also connected to the router, server works
Iptraf shows no traffic on eth1

Hope I haven't confused you as I have thoroughly confused myself.
